Autism Spectrum Disorder01:19

Autism Spectrum Disorder

1.3K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

The Electromagnetic Spectrum02:37

The Electromagnetic Spectrum

65.7K
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

The Electromagnetic Spectrum

33.9K
Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

IR Spectrum01:19

IR Spectrum

2.3K
When infrared (IR) radiation passes through a molecule, the bonds stretch or bend by absorbing the radiation. This absorption creates the molecule's absorption spectrum, which is the plot of its percentage transmittance versus wavenumber.
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...

Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

19.8K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Area of Science:

  • Neuroscience
  • Psychology
  • Computer Science

Background:

  • Autism Spectrum Disorder (ASD) is characterized by social communication deficits and repetitive behaviors, often involving complex cognitive mechanisms.
  • Understanding cognitive heterogeneity within ASD is crucial for targeted interventions and research.

Purpose of the Study:

  • To identify and characterize cognitive subtypes within the Autism Spectrum Disorder (ASD) population.
  • To explore the neural underpinnings of these identified subgroups using functional brain imaging.

Main Methods:

  • Utilized a Functional Random Forest (FRF) machine learning model trained on cognitive task data from 47 children with ASD and 58 typically developing (TD) children (ages 9-13).
  • Applied community detection algorithms to a subject proximity matrix derived from the FRF model to identify subgroups.
  • Analyzed resting-state functional connectivity magnetic resonance imaging (rsfcMRI) data to examine brain system differences between diagnostic groups and identified subgroups.

Main Results:

  • The FRF model achieved 72.7% accuracy in classifying ASD, with 80.7% specificity and 63.1% sensitivity.
  • Identified 3 distinct ASD subgroups and 4 TD subgroups with unique behavioral profiles.
  • Found significant differences in functional brain connectivity within and between systems (cingulo-opercular, visual, default, somato-motor, dorsal attention, subcortical) primarily driven by specific ASD subgroups.

Conclusions:

  • The FRF approach successfully identified distinct cognitive subtypes within the ASD population.
  • These subtypes exhibit unique behavioral and functional brain connectivity patterns, highlighting the heterogeneity of ASD.
  • The findings suggest that machine learning and neuroimaging can effectively parse variations in brain mechanisms associated with ASD.
